The present invention relates to new and useful improvements in valves, and has more specific reference to a novel and simpliiied valve primarily constructed for use in systems employing various forms of abrasive.

In the grinding of plate glass various abrasives such as sand, garnet, carborundum, etc., are maintained in suspension in water, and are continuously circulated through a pipe at a relatively high speed, being tapped ofi' at frequent intervals for use. This continuous circulation of the abrasive creates a severe cutting action on the parts of the system containing the same.

Ordinary types of valves have not been found entirely satisfactory in these systems as the abrasives wear away parts thereof so that in a comparatively short time the valve leaks and it is necessary to replace the same. Thus, the action of the abrasives upon the valve parts is very detrimental and renders the life of the valve very short necessitating frequentrepairs and replacements. Although the particular valve provided by the present invention is primarily designed for 'use in such systems referred to above, it is in no way restricted to such use as it can be used wherever ordinary valves are now used.

It is an important object of the present invention to provide a valve which will eciently withstand the wear of an abrasive passing therethrough.

Another object of the invention is to provide a valve including a housing, and a compressible member contained within the housing whichis adapted to be compressed to control the effective opening thereof.

A further obj ect of the invention is to provide such an improved valve of the above character having a compressible liner, and cooperating resilient members contacting with said liner for compressing the same whereby to control the effective opening thereof.

A still further object of the invention is to provide such an improved valve of the above character including a housing, a compressible member contained within the housing, and resilient members or pads contacting with said compressible member and cooperatprovide such an improved valve of the above character having a compressible liner, coop-l erating resilient pads contactingv with said hner2 and means for moving one of said pads relatlve to the other pad for controlling the effective opening of said liner.

Other objects and advantages of the invention will become more apparent during the course of the following description when taken in connection with the accompanying drawing.

In the drawing forming a part of this application and wherein like numerals are employed to designate like parts throughout the same,

Fig. 1 is a longitudinal section through a valve constructed in accordance with the present invention showing the same secured 1n position. f

Fig. 2 is a detail section'showing the arrangement of the compressible member and resilient compressing members or pads when the valve is closed, and

Fig. 3 is a similar view showing the valve in open position.

Referring now more in detail to the drawing, the numeral 5 designates one pipe of a system adapted to contain a flow of abrasive, said pipe being provided with a lateral outlet opening 6.

The valve provided by the present invention is designated in its entirety by the numeral 7, and comprises a casing or housing 8 provided with a central bore 9, the inner end thereof being substantially cone-shaped, and adapted to aline with the opening 6 in pipe 5 when the valve is secured in position.

The inner end of the housing is provided with an annular flange 10 which receives therethrough the opposite ends of a suitable U-bolt 11, passing around pipe 5. Suitable nuts 12 engaging the opposite ends of bolt 11 pipe 5.

The housing 8 contains a removable h'olldw 4 compressible member or liner 13,'l made of rubber or other suitable resilient material, which provides the regulatable passage for fluid through the valve. This liner is inserted into the housing through the inner enlarged end thereof, and the inner end of the liner is clamped betweenv the housing 8 and pi e 5, as indicated at 14..

hat portion of the liner indicated at 14 which is clamped between the housing and pipe serves also as a packing to prevent leakage of the valve. Even though the outer surface of the pipe 5 be somewhat uneven or roughened, the liner can be readily comressed to provide a tight lit and prevent eakage. Also,'it will be noted that the inner end of the hollow liner 13 has an inner diameter sliohtly eater than that of the outlet 6 Whic permits av free flow through the valve and creates a flushing action to prevent clogging of the valve. y l

The housing 8 is further providedwith a lateral opening 15 and surrounding this openf ing is a boss 16 through which is threaded the screw plunger 17, carrying at its inner end a valve head 18. This valve head 18 is formed with an under-cut groove within which isremovably secured the resilient compressing member or 'pad 19 formed of relatively soft rubber or other suitable resilient material and which member or` pad acts to compress the liner upon rotation of the plunger 17. The valve head 18 is detachably secured to the lunger 17 by means of pins 20 and should 1t be desired to remove the head 18 or plunger 17, it is simply necessary to remove the pins 20. The compressing member or pad 19v is adapted to snugly fit within the under-.cut groove in the valve head 18 and 1s effectively secured therein by the resilient nature thereof.

The housing 8 is further provided with a Vsecond opening 21 diametrically opposite the opening 15 and received within the said opening 21 is a plate 22 removably secured in position by suitable screws or the like 23. The inner surface of the plate 22 is also provided with an under-cut groove within which is removably secured asecond resilient compressing member or pad 24 similar to and adapted to cooperate with the first compressing mem-' vber o r pad 19. `The second compressing member or pad is also secured in position by the resilient nature thereof.

It will be seen that the abrasive within the pipe 5 can readily flow therefrom through the opening 6 into and through the valve and that this flow of abrasive through the valve can be readily controlled by simply rotating the plunger 17 to compress or release the liner 13. The liner 13 which, as stated, is formed 0f rubber or other suitable material will efmetallic valve head contacting with the linerv has failed to satisfactorily and completely compress the liner to close the valve with the result that a small amount of the abrasive would leak therethrough even whenv the valve was closed.

According to the present invention however, the cooperating compressing members or pads 19 and 24 are, as stated, formed of a suit- Y l able resilient material preferably relatively soft rubber and it will be apparent that compressing members or pads formed of such material will not injure the compressible liner nor tend to wear away the same as quickly as they would were the of metal. Moreover, when the resilient member or pad 19 is moved to :compress the liner 13, the saidA members or pads 19 and 24 will conform to the natural curvature of the liner as clearly shown in Fig. 2. This will not only result in a more uniform distribution of the pressure exerted on the. compressible liner but will furthermore serve to entirely compress the said liner to close the valve with the result that the flow of abrasive therethrough will be completely shut olf and danger of any abrasive leaking therethrougheliminated.

It is to be understood that the form of the invention herewith shown 'and described is to be taken as the preferred embodiment of the same, and that various changes in the shape,
